Tutorial - Random Maze Generation Algorithm in Javascript

I recently began working on a mobile game, more info of which will be coming as it gets closer to a release date. One of the central points of the game requires generating random mazes in a variety of sizes. This is a fairly well known concept in computer science, and there are a number of different algorithms which can be used to provide the maze. However, in my research, I came across few good tutorials on what exactly these algorithms did. As any developer knows, understanding what an algorithm does step by step is important to utilizing it in your own programs. Merely copying and pasting a function from some other site will invariably lead to convoluted code surrounding that function in order to get the parameters you need from it, and can lead to many problems down the road when a problem arises with that function. And believe me, a problem will always arise.
